What is accounting and why do we need it?

Before any entry, any ledger and any statement, there is one question: what is this whole thing for?

Chapter 1 · Lesson 1 of 58 min readBeginner level

Picture a trader who buys and sells all year, then is asked at the end of it: did you make a profit or a loss? How much do you own? How much do you owe? If he has not recorded what happened as it happened, his answer can only be a guess. Accounting is the organised alternative to guessing.

1 What is accounting?

Accounting is a system for measuring, recording and summarising an organisation’s financial events, then communicating them to whoever needs them as reports that can be understood and acted upon. It rests on four successive steps:

1
Recording

Evidencing every transaction with a supporting document

2
Classifying

Gathering similar transactions into accounts

3
Summarising

Producing the financial statements at period end

4
Interpreting

Analysing the numbers and giving them meaning for the decision maker

The accounting cycle: from financial event to decision

The idea in one line

The purpose of accounting is not the numbers, but the information drawn from them.

2 Who uses accounting information?

Users fall into two groups: those inside the organisation who need daily detail to run it, and those outside it who need a trustworthy picture on which to base a decision.

UserInternal / externalWhat they are looking for
Owners and partnersInternalHas their wealth grown? How much can be distributed?
Executive managementInternalWhere are resources spent? Which activity earns and which loses?
Banks and lendersExternalCan the business repay the financing on time?
Government authoritiesExternalThe accuracy of returns and statutory obligations
Potential investorsExternalIs this business worth investing in?
SuppliersExternalShould this customer be given credit terms?

3 Accounting and bookkeeping are not the same thing

The two are often confused. Bookkeeping is executional work limited to recording transactions accurately and in order. Accounting is wider: designing the system in which they are recorded, choosing the correct treatment, producing the statements, and reading what the numbers mean.

  • Bookkeeping answers: what happened?
  • Accounting answers: what does what happened mean, and how does it affect tomorrow’s decision?

4 Branches of accounting

Accounting branches out according to its purpose and the audience the information is directed to:

  • Financial accounting: produces standardised statements for external parties under published standards.
  • Managerial and cost accounting: internal reports for management, with no mandatory format, aimed at decisions and control.
  • Tax accounting: measuring the tax liability and preparing returns under the applicable regulations.
  • Zakat accounting: determining the zakat base and calculating it for the entities subject to it.
  • Auditing: an independent examination that gives the reader confidence in the statements.

5 The accounting equation: the heart of the system

Everything a business owns came from one of two sources and no third: either from others, making it a liability, or from its owners, making it equity. From this comes the equation that never breaks:

Assets = Liabilities + Equity — two pans that stay level however many transactions occur

Worked example

Saad starts a business by depositing 100,000 of his own money into the company account, then takes a bank loan of 20,000, and then buys equipment for cash at 40,000.

ItemAmountClassification
Cash at bank80,000Asset
Equipment40,000Asset
Total assets120,000—
Bank loan20,000Liability
Capital100,000Equity

Notice that buying the equipment did not change total assets — it only converted cash into equipment. And the equation balances: 120,000 = 20,000 + 100,000.

6 The assumptions and principles the numbers rest on

For statements to be understandable and comparable, a set of assumptions and principles is agreed and followed by everyone. The most important are:

  • Business entity: the business is separate from its owner, so his personal spending is not a business expense.
  • Going concern: the business is assumed to continue operating unless there is evidence to the contrary.
  • Accounting period: the life of the business is divided into periods — a year or a quarter — so results can be measured regularly.
  • Accrual basis: revenue and expenses are recognised when they actually occur, not when cash is received or paid.
  • Disclosure: any information that affects a reader’s decision is shown in the statements or their notes.
  • Prudence: assets and revenue are not overstated, and liabilities and expenses are not understated.

A common mistake

Mixing the owner’s money with the company’s money is the classic error in small businesses, and it corrupts the whole set of statements because it breaks the business entity assumption.

7 And who sets these rules?

Treatments are not left to each accountant’s judgement; they are governed by published standards. The most widely adopted internationally are the International Financial Reporting Standards (IFRS). In Saudi Arabia the Saudi Organization for Chartered and Professional Accountants (SOCPA) oversees the adoption of these standards and issues the related requirements, together with a specific standard for small and medium-sized entities.

Lesson summary

  • Accounting is a system for measuring, recording, summarising and interpreting financial events.
  • Its users are of two kinds: inside the business to run it, outside it to trust it.
  • Bookkeeping is an executional part of accounting, not a synonym for it.
  • The accounting equation — Assets = Liabilities + Equity — never breaks.
  • Assumptions and principles make statements understandable and comparable between businesses.

8 Test yourself

Three quick questions

Choose the answer you think is correct — the result appears immediately.

1. A business buys a vehicle for cash at 60,000. What happens to total assets?

2. The owner pays for a personal trip from the company account. Which principle is breached?

3. Goods are sold on credit in December and paid for in January. Under the accrual basis, when is revenue recognised?
